Celebrating their return
Cornish choughs Celebrating their return Ten years ago, wild choughs returned naturally to Cornwall This is their story “And mark yon bird of sable wing, Talons and beak all red with blood; The spirit of the long -lost king Pass’d in that shape from Camlan ’s Flood!” Richard Bedford R.S. Hawker, The Wrecker 1846 The return In 2001 the unexpected happened - choughs returned to Cornwall. They were not re-introduced, but wild birds, wandering Celts that found a new home and settled at the Lizard. Andy Hay (rspb-images.com) It had been nearly 30 years since the last true Cornish chough perished, and over 50 years since they successfully bred in Cornwall. A handful of sightings over that period, even two choughs staying for a few months, had raised hopes, but most people didn’t think they would ever see them return for good. What a difference a decade makes! Walk around the Lizard and Land’s End peninsulas today and you will have a good chance of seeing a Cornish chough. A Celtic crow From the mid 1800s habitat loss and persecution meant choughs had started to disappear from Cornwall and elsewhere in the south west but they still clung on in other Celtic countries. This map shows where there are choughs today (orange dots) and where they were once found (yellow dots). You can see what a strategic position Cornwall and Devon hold within the chough’s range in north west Europe. Current breeding locations Historic breeding locations Arthur ’s crow Legend also suggests that King Arthur did not die in battle; instead his spirit was reincarnated into the Cornish chough. “And mark yon bird of sable wing, Talons and beak all red with blood; The spirit of the long -lost king Pass’d in that shape from Camlan’s Flood!” An lavar koth yw lavar gwir Nevra dos mas a daves re hir Mes den heb taves a gollas y dir. The old saying is a true saying Never did good come of a tongue too long But a man without a tongue loses his land. Collected for Edward Lhuyd circa 1700 from the Vicar of Lannyust/St Just in Penwith ^ Williams Sian Henry Harris’s Cornish Saints and Sinners retells some traditional explanations for the chough’s red legs and beak. Thus we learn variously that the chough heard about a possible liaison at court between Jenefer (or Guinevere) and Lancelot that ‘…made him turn red in the beak’, he killed a potential assassin of the king (covering his beak and legs in blood) for which his family were knighted and, of course, he became a vehicle for King Arthur’s soul when he died. Paloresow kernewek Arta Keltek a wren ni oll omglewes Gans dehwelyans lowen a’gan balores Hag dre ilow dasserghys a’n taves. Once again we all feel Celtic With the happy return of our chough And through the reborn music of the tongue. Pol Hodge for Maga 2011 Most modern retellings of Arthurian legend suggest he will one day return. Alongside this story of King Arthur and his transformation into a chough, is also the belief that King Arthur will always be there in his spirit form to lead the Cornish in times of need. Richard Bedford This extract from The Wrecker is said to mark King Arthur’s violent end, and his link with the Cornish chough with its iconic red beak and talons is clear. A new generation of Cornish choughs A leisurely walk from Southerly Point to Kynance Cove is an excellent way to see choughs—you will almost always hear them first, as their distinctive “cheeow” call echoes around the cliffs. Andy Hay (rspb-images.com) Richard Bedford These two birds are the pioneers that arrived in 2001. As founders of Cornwall’s new chough population they have become 21st century Cornish emblems. Just making a comeback is not enough though. These two birds had the hopes and expectations of Cornishmen and women on their shoulders (wings?). Would they, could they, be successful? Of course they were! By now, everyone has surely heard that Arthur’s crow, the Cornish chough, is back. For 10 years this pair has been faithful, they are hardly ever seen more than a few feet apart. In nine breeding seasons they have successfully raised 36 chicks, many of whom are now producing young of their own at other sites in Cornwall. By now, in 2011, they must be at least 12 years old, and they may breed until they are 16 or older. The male chough has had his fair share of narrow escapes. In 2007 he seriously injured his leg protecting his newly fledged family from a herring gull (who was protecting its chick). For days he could not walk on his injured leg but, with chicks to feed, he struggled on and eventually it healed, albeit with a definite ‘kink’. A chough’s year March Building a nest (or renovating last year’s with a few twigs of sea carrot). High summer Juveniles perfect their flying moves and escape the parents. April Female lays eggs and sits tight for 21 days. Male feeds female at nest. Autumn and winter May Both adults busy making foraging trips to find food for hungry mouths. Exploring the coast to find good places to feed, places to revisit for many years to come if they are lucky enough to survive. Early June Chicks make their first appearance, spending a week or so ‘bouldering’ as they gain confidence to fly. Andy Hay (rspb-images.com) The Lizard pair 2006 - a second pair! Choughs only breed once each year. Two to five eggs are laid. This Cornish nest is crammed with five chicks, approximately four weeks old. John Eastman Tony Cross This female on the left in the photo above was almost certainly the third bird that arrived in 2001. She was known as ’the gooseberry’ because she hung around with the Lizard pair. An older, experienced bird, she often flocked with the young choughs and in 2006 paired with the colour ringed bird you can see (a bird from the 2004 brood). This partnership was successful and they raised young in 2006 and 2007, a total of nine chicks. Some of their offspring have continued the population recovery by forming pairs of their own. Miner birds “It ’s exciting seeing choughs fly overhead so close -it always lifts your spirits.” A tin miner, a fisherman and a chough all featured on Cornwall County Council’s coat of arms (only the chough remains on the new Cornwall Council’s coat of arms). All three are shadows of their former glory in the Duchy, but the chough is now back where it belongs. Its resurgence gives the Cornish people renewed hope for the future and a living symbol with which to identify. Lindsey Butterfield, National Trust Ranger, west Cornwall. Fishermen are often the first to spot choughs when they arrive in new places. Mark Williams and others who fish out of Cadgwith often see choughs as they pull up their pots. The Crowns, Botallack, often used by roosting choughs. Andy Hay (rspb-images.com) Andy Hay (rspb-images.com) Two of the nest sites used by choughs, and many of their roost sites too, are in old mine workings. Adits and shafts hewn out of rock to extract tin and copper make great artificial caves. St Piran bling How do we know so much about the choughs in Cornwall? Every nesting attempt each pair makes is well watched. By noting the behaviour of parent birds we can tell when eggs have been laid and hatched. When observations show that chicks are about three weeks old, Tony Cross, a specially licensed ringer and chough expert, comes to Cornwall from Wales. So far he has been able to ring all 55 chicks fledged in Cornwall. Each youngster is fitted with a unique combination of colour rings so that it can be identified throughout its life. This is how we learn about their everyday lives, which birds are surviving, who pairs with whom, how far they go, and a whole lot more. Matt Sallis Andy Hay (rspb-images.com) Since 2008 Cornish choughs have been fitted with one black and white striped ring as well as two other coloured rings on their other leg. Black and white are the colours of the cross of St Piran (the Cornish flag) very appropriate! How far do the choughs travel? In 2008, a pair of choughs was spotted doing what choughs do naturally in spring time... Close inspection of the colour rings of the two birds revealed that they were in fact both male. In the bird world it’s not unusual for young birds to practise before they reach maturity, but these two have formed a very strong bond. They are still together even though they often join a mixed-sex flock in winter with the opportunity to find a new mate. We know choughs can travel long distances and cross seas (the birds that arrived in Cornwall would have had to fly at least 100 miles from Brittany, and further if they were from Wales or Ireland). From colour ringing we know that one young bird born at Southerly Point in 2010, although sadly found dead, had travelled as far as Portwrinkle on the south coast of Cornwall. Other choughs have been spotted near St Ives and Polzeath. How do you sex a chough? When they are being ringed, the wing, leg and weight measurements for females are generally smaller than those for males. Once adult, females are usually smaller with shorter bills; this is noticeable in the field if you see male and female side by side. This newly fledged female raised on the Lizard, now two years old, has a territory near Land’s End. Andy Hay (rspb-images.com) Martin Lenney Has ringing revealed anything surprising? Know your crows red bill and feet of the chough make it quite unlike any other member of the crow family. Julian Hodgson A chough could easily be overlooked since its more familiar relatives are very common. In fact, the word chough was previously used in Cornwall for jackdaws too. The two species share an affinity for coastal slopes and cliff ledges, but look more closely and the striking Other corvids include rooks, crows, jackdaws, magpies and jays; all very intelligent and resourceful birds. Broad, `squarish’ wings with deeply `fingered’ tips and a light and bouncy flight are characteristic of this agile crow. Sometimes they seem to fly right through crashing waves, showing a mastery of the air no other crow has. When feeding they do not stand as upright as a crow. And of course they have bright red legs and bill (youngsters have orangey-brown legs and bill). Massive (bigger than a buzzard) all-black bird — look out for its diamond-shaped tail, shaggy neck, large bill and low, croaking call. Breeds on cliff ledges and builds a large nest of sticks. Palores, Another all-black bird frequently seen along the coast, larger than a chough. Not sociable like choughs. With its powerful, chunky black beak, the carrion crow in silhouette looks very different from a chough. Colin Scott Rook Similar size to carrion crows, but more often seen in flocks and usually found on farmland. Rooks strut, have `trousers’ and a high forehead with a striking greyish white base (no feathers) to their bill. Bob Sharples Nick Upton (rspb-images.com) Carrion crow Andy Hay (rspb-images.com) Jackdaw Perky and always busy, jackdaws have piercing, beady pale blue eyes and heads of silvery grey feathers. Their ‘Jack’, ‘Jack’, ‘Jack’ calls echo around cliffs and old buildings and they frequently come close to people. Jackdaws live in loose colonies and are smaller than choughs. ^ Williams Sian Chris Gomersall (rspb-images.com) Chough Raven meaning digger, is the old Cornish name for chough. Other names for the chough in Cornwall are Killegrew, chaw, and culyek crow (gore cock, another allusion to its red bill and legs). Elsewhere they were (and are) variously known as chofe (Devon), bran Gernyw and bran goesgoch (Wales), and Cornwall kae (Scotland). Choughs were often kept as pets and in the 15th and 16th centuries they had quite a reputation. Their mischief included filching money and small objects and stealing lighted candles and embers, which they then dropped onto thatched roofs. The chough’s scientific name, Pyrrhocorax pyrrhocorax, comes from Greek/Latin meaning fire crow or fire raven, undoubtedly a reference to their reputation as pyromaniacs and that flaming crimson bill. People power Watching you watching them Andy Hay (rspb-images.com) Over the last 10 years a weather-hardy gang of more than 100 volunteers has spent thousands of hours watching and monitoring the choughs at all their nest sites. Round-theclock surveillance for these lucky birds has increased their chances of survival and united a diverse group of people in enthusiasm for choughs. With their individual characteristics and antics, the birds keep volunteers enthralled and entertained, as do the occasional sightings of dolphins, basking sharks and seabirds. You don't have to be Cornish or a birdwatcher to do your bit for choughs, you just need a good set of waterproofs and a flask of tea! RSPB Investigations Officer with seized egg collection A pair in west Cornwall near St Just has so far raised nine chicks. David (pictured) and a group of 30 other volunteers help protect their nest. “Whenever I’m watching our choughs I still get a shiver up my spine. It’s almost as if I’m witnessing an impossibility, as if I’m just out for a walk and spot a dodo, or the beast of Bodmin Moor, or a Tasmanian tiger. But this morning is particularly special, because the choughs have only just got up, and we’ve been keeping them safe all night, and we’re the only ones in the world who can see them right now. It’s intimate. Of course, the birds are just going about their daily business of survival. For them every day is life and death. But I like to think they’re saying: Thanks mate.” Pete Cross, author and volunteer Criminals beware Sadly there is an extra level of threat facing choughs as there are still people who collect wild birds’ eggs. This has been illegal since 1954 but nests still have to be protected 24 hours a day when the female is sitting on her eggs. Egg thieves are prosecuted every year in the UK and vigilance is still necessary for Cornwall’s birds. Tread gently The coast is a busy place, not just for wildlife but for people too. We all appreciate somewhere to escape and have fun, but need to be careful that our activities do not adversely affect the daily lives of the creatures for whom the coast is home. A photo of a chough is a lovely souvenir, but get too close and you may disturb the bird from feeding. And take care to watch for choughs when letting your dog off the lead. David Mann on dusk watch Andy Hay (rspb-images.com) The natural world is an uncompromising place for wildlife and this is especially so for choughs in Cornwall, where their first tentative steps towards natural re-colonisation still hang in the balance. Natural predators such as the peregrine can take an unwary adult chough, and young chicks are vulnerable as their curiosity and lack of experience bring them into contact with ravens, gulls, foxes and all manner of other dangers. As is normal and expected for all wild birds, not all the chicks fledged so far have survived. What’s their story? The people here and many more have volunteered over the last 10 years to help choughs in so many different ways. Thanks to those that have given time, goods, tea, shelter, support, money, skills and more; their choughs are faring well. “I m’ glad that choughs have returned to Cornwall and to where I live, that s’ why I m ’ involved.” Andrew Trezise “April to June means not only being in the team protecting the choughs, but also sharing my knowledge of them with inquisitive visitors on the coast path.” "Ten years later, still walking the cliffs and that wonderful call and bouncing flight still thrill me every time. What a privilege to share their home!" Alix Lord “There is no greater pleasure than watching the adult pair overseeing their fledglings emerge into the big wide world.” Nigel Kemp (pictured) Andy Hay (rspb-images.com) John Lancaster Chuffed to help It ’s not just conservationists and volunteers who have done their bit for Cornish choughs over the last 10 years, farmers have too. What are farmers doing? Why are cattle crucial? Cattle are choughs’ best friends. Choughs eat invertebrates and find them by probing with their beaks, so they need access to the soil surface. Cattle graze in a way that opens up vegetation, making it easier for choughs to catch beetles scuttling along the ground and find juicy cranefly larvae just under the soil surface and caterpillars hiding in shorter clumps of grasses and heather. Cattle dung harbours lots of grubs - perfect food for a chatter of hungry choughs. Farmers like Will Bowman, Robert Trezise and Vivian Penrose (pictured) have an important role in ensuring that the fields where choughs like to feed on their farms are in tip-top condition. Thanks to farmers and their enthusiasm for helping these birds, there are now more chough-friendly feeding areas around the Cornish coast. Tony Blunden For some farmers this means taking on the extra responsibility of restoring habitat along the cliff slopes. Tackling excess bracken, gorse and blackthorn to bring back a mosaic of shorter, more open vegetation means a greater variety of plants and other wildlife can thrive. National Trust Working together for choughs The RSPB, the National Trust and Natural England, partners in the Cornwall Chough Project, work in many different ways for choughs. Many National Trust tenants who farm around the coast have Environmental Stewardship agreements with options to manage their land specifically for choughs. National Trust staff and volunteers manage a herd of ponies on the Lizard to help keep the vegetation just right for many rare and colourful plants, and choughs. Natural England’s management for wildlife on the Lizard National Nature Reserve means grazing cattle and ponies are now a familiar sight. Natural England has championed choughs in Cornwall. When planning and implementing Stewardship schemes its advisors ensure where possible that choughs are taken into consideration. Andy Hay (rspb-images.com) RSPB staff advise farmers, helping them access Stewardship schemes so they can manage their land with benefits for wildlife and the historic environment too. “Adrian Thomas (seen here on the left with National Trust and Natural England staff) farms near St Just and said more than 10 years ago “You’ll never get choughs back here, not in a month of Sundays!”. But we did, with his help and that of other farmers around The Lizard and West Penwith peninsulas.” Peter Bowden, Natural England A ‘must do’ in Cornwall Finn and his winning chough biscuits Thousands of people have made a special visit to Southerly Point to catch a glimpse (and often be treated to a low-level fly-past) of the Lizard pair. Choughs are now a ’must do’ along with the Eden Project, Tate St Ives and a Cornish pasty. A close encounter with wild choughs is often the highlight of most people’s visit – and the reason for future trips. Although lots of people have been directly involved since the choughs’ return, many more have benefited from their continuing presence. An economic study in 2004 found that choughs brought a significant amount of income into the local economy each year. Since then interest in the choughs has blossomed. Look out for really lovely chough-themed souvenirs produced by local craft makers. “It means a lot to the National Trust s’ staff, volunteers and tenant farmers to see their hard work paying dividends for choughs and other wildlife.” Rachel Holder, National Trust Ranger, the Lizard. Andy Hay (rspb-images.com) The return of the chough has inspired local musicians, artists and authors, showing there is still a place for Cornish choughs in people’s lives despite the many changes that have occurred since these birds last haunted the cliffs. Now the choughs are becoming more well known, walks, talks and other events are spreading their story further afield. Cornish associations abroad are especially interested in the latest chough news. To enquire is human Andy Hay (rspb-images.com) So how do you help children to understand and bond with birds, plants, creepy crawlies and the great outdoors? By letting them get freshly cut hay entangled in their hair, be on a cliff edge as dawn breaks, explore fields at night by torchlight and scrape the odd knee - that’s how to inspire children about science, their local patch, local culture and wildlife. They may not grow up to be astronomers or conservationists, but they will respect and appreciate their natural surroundings. What does a chough think? Why are they black? Do they fly at night? Do you know? Encouraging children to think about these conundrums helps them start to really understand the world and how it works. And that understanding and enjoyment will inspire a new generation to look after Cornwall’s special wildlife. Chough Club (children from St Just Primary School pictured), started by Therese Clemo and the RSPB, enables children to explore, enjoy and appreciate the natural world. Jo Clegg Our natural environment is a precious asset. The survival of its wildlife is dependent on people looking out for it, not just now, but for the long haul – and the need for care and understanding applies especially to choughs. Are they back for good? Are you inspired to go in search of choughs? steady. They have been my life for the past decade, long may this continue.” Claire Mucklow, RSPB Chough Project Manager Andy Hay (rspb-images.com) Although it’s still early days for the Cornish choughs, we hope that with continued assistance from everyone—volunteers, farmers, conservation partners, local communities and visitors—their numbers will increase and spread around Cornwall’s coast. A young pair of choughs has set up territory on the north coast of Cornwall, a huge leap along the coast for them, and in February 2011 an ‘incomer’ made landfall on the Land’s End peninsula, an unringed bird wandering in from another Celtic country to find a home. There have been some sightings over the last few years of choughs along the north Devon and Somerset coasts too, birds known from their colour rings to be from the Gower Peninsula in Wales. All these developments show that wild choughs are continuing their comeback in the south west, crucially linking this small Cornish population with those in Brittany, Wales and Ireland. With the Cornish chough now reestablished in Cornwall and successfully breeding, there is interest worldwide in this charismatic member of the crow family. In winter the choughs sometimes flock together and roam the coastline. Feeding parties are often seen around Kynance Cove and Land’s End. Andy Hay (rspb-images.com) “10 years ago we didn ’t dare hope we’d be where we are today. The choughs’ progress is slow but Since choughs rarely travel far inland, the coast path is your best vantage point and late June is the very best time as there will be newly fledged chicks out and about. Remember to listen for ‘cheeow cheeow’. Wings tucked in and rollercoaster swoops and dives make choughs the show-offs of the crow world; and we bet they make you smile as they tumble joyously past. If they land close by, just sit quietly; they may settle and come closer. Please can you help give Cornish choughs a safer future: • Volunteer your time to help with an aspect of the Project. • Donate money to help keep the Project running. • Tell people about choughs, and how much they mean to you. Tony Blunden • If you see a chough, tell us when and where. • Join the RSPB and National Trust to show your support.
